CLOSURE DEVICE.

Specification of Letters Patent.

"Patenten Jan. is, 191e.

Application filed March 22, 1915. Serial No. 16,162.

To all whom it may concern Be itknown that I, ELIJAH H. Davis, a citizen of the United States, residing at Midland, in the county of Allegany and State of 'Maryland, have invented certain new and useful Improvements in Closure Devices, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to closure devices and has relation more particularly to a device of this general character especially designed and adapted for use in 'connection .with containers; and it is an object of the inventidn to provide a device of this general character having novel and improved means whereby the discharge opening of a container may be effectively sealed with convenience and facility.

Furthermore, it is an object of the invention to provide a novel and improved device of this general character normally carried by the container with which it is adapted to coact and of such a nature as to be highly sanitary. V

The invention consists in the details yof construction and in the combination and arrangement of the several parts of my improved closure, device whereby'certain .important advantages are attained and the device is rendered simpler, less expensive and otherwise more'convenient and' advantageous for use, all as'will be hereinafter more fully set forth. n

The novel features of thev invention will be carefully denedin the appended claims. c In order that my invention may be the better understood, I will` now proceed to describe the same with reference to lthe accompanyingdrawings, wherein- Figure 1 is an elevational view illustrating a closure device constructed in accordance with an embodiment of my invention,

the coacting container being disclosed infragment; Fig. 2 is a vertical sectional view taken through the device as disclosed in Fig. l, with the clampingmember in elevation; and Fig. 3 is a sectional View taken through a cap member constructedv in accordance with a further embodiment of my invention.

As disclosed in theaccompanying drawings, C ydenotes a container provided with a discharge neck vN and of such 4configuration in longitudinal sectionto afford an an-v nular shoulder 1 at afpredetermined point inwardly of the outer end of the neck and with the periphery of t-he neck intermediate 'bevel 2 so that when said'cap member is in applied position, a perfect seal is assured whereby the possibility of theJ contents of the container being'accidentally discharged with the cap in applied position is eliminated. -The outer marginal portion of the flange ai and its inner wall is provided 'with an annular groove or channel 5 in which is adapted to be secured `a gasket whereby an effective sealing of the container by the cap member 3 is further assured. The gasket 6 may be of rubber, cork or any other material which may be employed with facility. The inner surface of the .cap member 3 adjacent the flange 4 is provided with an annular groove or channel 7 concentric tothe axial center of the member '3 and in which is positioned the gasket 8 of suitable material, ,said gasket being arranged for contact with the outer edge of the neck N when the member 3 is applied and serving for a purpose which is believed to be Aself-evident.

Producedin the outer surface of the member 3 at the axial center thereof is the threaded recess 9 in which is adapted to be engaged the llower extremity of the post or arm 10, said post being provided with an elongated longitudinally disposed slot 11 through which is directed the clamping member 12, 'herein set forth as substantially U-shape in form, having ,its free extremities pivotally engaged with the eyes or loops 14 carried by the lever oryoke member 15. vThe lever or yoke member 15 is pivotally engaged with-the anchoring wire or member 16 suitablysecured around the neck N inwardly of and immediately adjacent the annular shoulder 1, hereinbefore L.'

. in the clamping member 12 effecting the desired engagement of the member upon the neck N.

Loosely mounted upon the postlO are the reversely disposed caps 17 positioned interlio mediate the clamping member 12 and the y member 3 and arranged between the caps 17 is an expansible member 18, herein disclosed as a conventional coil spring, embracing thepost 10. The expansilole member 18 serves tofacilitate the application of the member 3 inoperative position and also assists in its removal, as is believed to be selfevident to those skilled in the art to which my invention appertains. I also find it of advantage to have the portion of the clamping member 12 disposed through the slot 11 v of the post provided with the downwardly disposed substantially V-shape extension 19 extending within the perforation 2O of the upper cap 17 through which the post 10 is directed whereby the requisite relative movement of the caps 17 is facilitated under the influence of the lever or yoke member-,15.

The member 3 may be formed of any matei'ial which may be employed with success,

but in certain instances I find it of advantage to employ a member as illustrated in Fig. 3 of the accompanying drawings, and wherein said member is disclosed as compris'ng a shell21 of netal and of desired configuration and provided withl a filling 22v of Celluloid or other sanitary substances,

said shell being perforated, as indicated at \23,gwhereby the filling and lbe.-f1rmly united.

the shell may lFrom the foregoing description, it is thought-to 'be obvious that a closure device constructed in accordance with my inventionr is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with Vwhich it may be Y assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from theprinciples and spirit thereof and for this reason I do not wish to be understod as limiting myself the lprecise 'Copies of this tfent may be obtained for arrangement and formation of the several parts herein shown in carrying out my invention in practice. i

I claim:

1. In combination with a container provided vvith a discharge neckfa closure member therefor, a post` projecting from the closure member at substantially its axial center and provided with an elongated slot, a clamping member disposed through the slot of the po'st, operating means carried by the 55 container coacting wlth the clamping member, reversely disposed caps loosely mounted upon the post and interposed between the A y clamping member and the closure member,

In combination with a container proi clamping member disposed through the slot of the post,yoperating means carried by the y container coacting with the clamping meinber, reversely disposed caps loosely mounted upon the post and interposed between the clamping member'and the closure member, and anexpansible membery interposed between the caps, the portion of the clamping member disposed through theslot of interlocking with the adjacent cap.

In testimony whereof I hereunto aiiix my signature in the presence of two witnesses.
